1. Preliminaries We (the RAF in World War II) want to know the number of warplanes fielded by the Germans. That number is N. The warplanes have serial numbers from 1 to N, so N is also equal to the largest serial number on any of the warplanes. We only see a small number of serial numbers (assumed to be a random sample with replacement from among all the serial numbers), so we have to use estimation. Question 1.1 Is N a population parameter or a statistic? If we use our random sample to compute a number that is an estimate of N, is that a population parameter or a statistic? Write your answer here, replacing this text. Check your answer with a neighbor or a TA. To make the situation realistic, we're going to hide the true number of warplanes from you. You'll have access only to this random sample:

Accepted Solution

Answer:N is a population parameter; the estimate of N is a statistic.Step-by-step explanation:A measure of a population is called a parameter.  The population is the entire set we are measuring.  In this problem, N is the total number of warplanes fielded by the Germans.  Since it is the total, it is a population, making it a parameter.A measure of a sample is a statistic.  This means an estimate of N based on a sample would be a statistic.
